ANDREW EKMAN, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO GRAND RAPIDS BRASS COMPANY, F GRAND RAPIDS, MICHIGAN, A CORPORATION 0F MICHIGAN.

DOOR LATCH.

Application led February 19, 1925.

To [1]] whom t may concern.'

lle it known that I, ANDREW EKMAN, a subject ot' the King of'S\\'eden, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Door Latches, of which the following is a specification.

The present invention relates to' door latches; and its object is to provide improved means for unlatching the saine from the opposite side of the door.

This and any other and more speciiic objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure or structures hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a front or face view of a door latch;

Figure 2 is an end View thereof;

Figure 3 is a transverse horizontal sectional view of a portion of a swingable door and of its jamb, showing in top plan View the said latch mounted on the doors outer side, and showingl means for unlatching the same from inside the door;

Figure 4 is a face View of a block or metal casting and levers ulcrumed thereon;

Figure 5 is a right-hand side view of the same;

Figure 6 is a front or face view of another form of door latch;

Figure 7 is an end view thereof;

Figure 8 is a transverse horizontal sectional view of a portion of a swingable door and of its jamb, showing in plan view the latch shown in Figures 6 and 7, and showing a modified construction of the means for unlatching the same from the doors opposite side, such modiied form of said means being particularly adapted to operate in connection with the form of latch shown in Figures 6, 7 and 8;

Figure 9 is a vertical sectional view ot' said door and jamb; and

Figure 10 is a front or face view of a block or metal casting and the levers of said moditied construction ulcrumed thereon.

In the accompanying drawings, a. swingably mounted dooras the refrigerator door l-is shown, carrying a latch 2 mounted on its outer side or surface adjacent the doors free edge. The jamb or frame of the door adjacent its free edge, and

Serial No. 10,207.

carrying the latchs keeper 3 is indicated at 4.

In Figures 1, 2 and 3 a latch of the form or type having a slidable latching bolt 5 is shown, while. in Figures G, 7, 8 and 9 a latch having a swinging or lever form of latehing holt 51 is illustrated, the form of the means for unlatching the latch from inside the door being somewhat ditferent in Figures 5l, 4 and 5 from that illustrated in Figures 8, 9 and 10.

In the construction or form seen in Figures 1-5: A block or inetal casting 6 secured as by screws passed through its openings 7 to the inner side of the door, carries levers 8 and 9 fulcrumed thereon. at 10 and 11, at right angles to each other. The short arm 12 of lever 8 engages under the arm 13 of lever 9. A rod 14 extends through the door, being slidable in the opening ,15 therethrough. The outer end 16 of the rod abuts on the inner side of the operating lever or handle 17 of the latch, and its inner end 18 abuts on the other arm 19 of the lever 9. It will be seen that, the block 6 being secured on the inner side of the door at a convenient elevation from the fioor, the long arm 2O of lever 8 may be readily pressed by the shoul der of a man carrying a heavy burden out ot the refrigerator room, and thus the door may be unlatched and pushed open, without the necessity of his laying down his burden or using his hands for this purpose.

Another form or modiied construction of the unlatching means especially adapted for use in connection with latches having swinging or lever-latch bolts is shown in Figures 6-10: In this form the lever 21 ulcrumed at 22 on the block or casting G1 has a long arm 23 extending through an opening 24 in the door and engaging the upper side o the handle portion of the latchinglever 51 of the latch 21, the shortv arm 25 of this lever 21 being engaged by the short arm 121 of the lever 81, fulcrumed at 101, whose long arm 201 is adapted to be pressed toward the door to operate the unlatching means.

A guiding extension 26 of the casting or block 6 extends through an opening 27 in lever 9 as shown in Figures 4 and 5.

The invention being intended to be pointed out in the claims, is not to be limited to or by details ot construction of the particu lar embodiment or embodiments thereofl illustrated by the drawings or hereinbefore described.

I claim:

1. In combination with a swingable door; a latch having an operating lever fulerumed on the outer side of the door; a lever fulerumed on the inner side of the door; a level` fulorumed on the inner side of the door and having an arm engaged by an arm of the second-mentioned lever; a slidable rod extending through the door and engaging the first-mentioned lever and engaged by the other arm of .the third-mentioned lever te swing the first-mentioned lever to unlatching position by the swinging movement of the second-mentioned lever.
